T all whom t viz-ay concern.'

Be it known that l, F ruimt O. HOAGLAND, a citizen of the United States, and resident of Bridgeport, in thevco'unty of Fairfield and State of Connecticut, have invented cer,-r tain new and useful Improvementsr in Oil Cups, otl which the following is a specifica'- tion. f f n rIfhis invention relates to new and useful improvements in oiling devices for pulley bearingdvwheel spindles and the like andincludes adjustable means whereby the oil in- 1 let may be readily opened and closed forfoiling purposes. l y

The object of the invention is to provide simple and inexpensive form of oiler through which lubricant may be supplied to a bearing and whereby .the same may be kept free from dirt, and particularly to provide a flush oiler, that is adapted to be mounted in the periphery of a pulley or other form of wheel7 so as to finish flush withthe surface thereof and thereby better adaptingit to he applied in the peripheral portion of a beltcarrying pulley or other elements to be oiled, where a'projecting oil cap would be objec tionable. c ,c

yAnother feature of the invention is to construct the same so as to form a commercial article which can readily be applied topulleys already in use or formed in the pulleys when originally manufacturing the same; further to provide means whereby the principal parts of the oiler may be readily removed for cleaning. the oil pocket and oil ports to the bearing, should thesameb'e nec` essary.

My invention also embodies certain other novel features of construction, combination and arrangement of parts substantially as disclosed therein and illustrated in the accompanying drawings forming part of this specification and in which,

Fig. 1 shows a sectional elevation of my improved Oiler shown in an open position.

Fig. 2 shows a central vertical section of a pulley having my improved oiler applied therein.

Figs. 3 and 4 show longitudinal sectional views of modified forms of myk invention thel same being made in two parts in a way to form the device completein itself and adapted to be inserted in a plain hole of a pulley.4

Figs. 5, 6, 7 and 8 show further slight modified forms of constructions Of Oilers and each mayv be of two parts and all adapted to be utilized and operated in the same manner as that shown in they preceding figures. y

,in Figs. 1 and 2 of the drawings l have shown my oiler applied yand positioned in the peripheral face of a belt 'pulley7 the outer end being iiush with the face of the wheel. It should be borne in mind, however, that theinvention is equally applicable toruseV in other places including not only .movable members,y but fixedy bearings where it is desir.- ahleto form a dust-proof oiler that will linish flush with or below ythe surface of the member in which the foiler ismounted.

Referring in detail tothe characters ofreference marked upon the drawings, 10l represents an ordinary type of belt pulley having an oil port 11 formedradially therein f through the web or spoke portion, said 'port communicating with the, shaft hole through the hub of the wheel and extending out in alignment with myoiler positioned in the pocket formed in the outer peripheral portion of the wheel. and 2, provide wit-hin the peripheral' portion of the pulley a special form of pocket to `receive an adjustable oiler member which is made operatably effective in conjunction with the pocket as will be understood from 'the further description to follow. This pocket is formed in radial alignment with the. oil port and is considerably larger in diamet'er.y and includes two threaded side wall portions` 12 and 13 l'iavi-ng an annular en: lai ement 14. formed therebetweenwhich is ofa sligl'itly greater depth than that of the lower threaded end portion of they pocket. These two threaded portions should both in clude a right hand thread of equal size and pitch so as to accommodate the same screw thread. The upper end of the pocket includes a further enlargement 15 to receivey the head 16 of the hollow adjustable screw 17.

The screw so-called is of special construction and serves to form an inlet for the lubricant and also a closure for t-he pocket. As will be seen, it includes a cylindrical shank portion 18, an enlarged threaded end portion 19 for engagement with the before mentioned threaded wall of the pocket. Itis further provided with a central longitudinal oil passage 2O therein that communicates with a side oil inlet 21 positioned immediately beneath the under portion of the head 16 of the screw so that when the same is run vAsshown'in both Figs. 1

out of the lower threaded socket portion 13 of the inlet hole the screw will be exposed and positioned to receive the spout of' an oil can, by means ot which the oil may be injected in the screw, oil pocket and port within the pulley. After this the screw may be again engaged with the threaded wall and turned in to close the opening as shown in Fig. Q.

It vtor any reason it is desirable to clean the port or socket the screw can readily be removed by first turning its threaded pon tion out oi' the lower threaded portion 18 to the free position shown in Fig. l and then by further lifting it and turning it to engage its thread with the upper threaded portion 'l2 it may be run out tor complete detachment.

In each oi' the constructions shown in Figs. 3 to S inclusive l employ a screw 17 having side and central oil passages through which the oil is admitted and directed to the oil port in the pulley. This screw includes one or more peripheral threaded portions 19a for engagement with the threaded portions l2 and i3 of the wall of the outer sleeve 10a which is adapted to be forced in to a plain hole, not shown, ot' a pulley and takes the place ot the special formation of the pocket shown in Figs. l and 2. The lower end of the screw shown in Figs 8, 4, 5 and 7 are provided with annular flanges 13b which are designed to prevent the complete disengagement of the screw from the sleeve and to limit the distance of' which the screws may be withdrawn for oiling purposes. The constructions shown in `Figs. V6 and 8 .are substantially like that shown in Figs. l and 2 except that they are designed to form an oiler complete, ready -for placement in a plain form of oil hole.

vFrom the foregoing it will readily be seen that my improved oiler includes an adjustable hollow screw havino` a communieating opening in the side be ow the head portion and provided with a suitable socket wherein it may be adjusted, and the amount ot said adjustment limited or temporarily arrested to permit oiling. Therefore l. do not wish to he limited. in the matter of detail or construction since as shown the principle of the invention may be successfully carried out with slight modiiications.

Having thus described my invention7 what l claim and desire to secure by Letters Patent, is

il. An oiler or the class described, including a casing having a pocket 'formed therein adapted to be closed by a screw and pro'- vided with a threaded and 'plain side wall portion, a hollow screw adjustably mounted in the pocket and having part only or' its periphery threaded to adjustably engage the threaded portion of the socketl and provided with means to limit its withdrawal movement, said screw further includingV a side ktilling opening below the head of the screw and positioned to be closed when the screw head is seated.

2. An oiler of the class described, including acasing having a pocket formed therein and yprovided with two threaded portions anda `plain side portion intermediate of the said threaded portions, a hollow screw adjustably mounted in the vpocket and having part only of its periphery threaded to engage either ot the threaded portions of the socket and'adapted to be disengaged when positioned between the said threaded portions, said screw further. including Va side iilling opening below the head of the screw to he closed when the screw head is seated.
